Fiscal Health Shows Improvement

Risks & Challenges Ahead

High reliance on excise & stamp duty which can be volatile.
Central grants falling sharply dragging on total revenue flexibility.
The state still runs a revenue deficit (1.3% of GSDP) - a lingering concern.

This growth enhances the state’s autonomy and resilience even as central grants decline. However maintaining this trajectory will require disciplined spending, better tax management and less dependence on volatile categories.
